Oh yes, four exclamation points for the fourth installment in a fantastic franchise. The trailer we've all been waiting for is now online, and you can view it above (courtesy of Yahoo) -- Indiana Jones and the Kingdom of the Crystal Skull. I don't even want to say anything about the trailer; I almost want the first reaction to come from you fans. This is a biggie. This isn't just another trailer for just another movie. This is Indiana Jones. This is Harrison Ford. This is Steven Spielberg. This is George Lucas. This is ... something we've been waiting 19 years to see. (How lame am I?) So take a breath. Clear the next couple minutes. Sit back, relax and enjoy ...

... then tell us what you think.

He's back in theaters on May 22.
